The Tech Castle

   What comes to mind when you think of a bot on Twitter? You probably picture a spammy account sliding into your DMs or a Russian troll farm pumping out fake news and conspiracy theories. Thanks in large part to misinformation campaigns waged on social media during the US 2016 election, a lot of people associate bots with this type of nefarious activity. They have good reason to: Twitter detects roughly 25M accounts per month suspected of being automated or spam accounts.

Twitter has an entire enforcement team dedicated to tracking down these accounts and banning them. But it’s not as simple as blanket-banning all automated accounts. Bots actually come in all shapes and sizes, and chances are, you’re already following one that you like. Like a COVID-19 bot...

  What Is Fog Computing Fog computing, also called fog networking or fogging, describes a decentralized computing structure located between the cloud and devices that produce data. This flexible structure enables users to place resources, including applications and the data they produce, in logical locations to enhance performance.   Fog computing maintains some of the features of cloud computing, where it originates. Users may still store applications and data offsite, and pay for not just offsite storage, but also cloud upgrades and maintenance for their data while still using a fog computing model. Their teams will still be able to access data remotely.   Fog computing, a term created by Cisco, also involves bringing computing to the network’s edge. However, it also refers to the standard for how this process should, ideally, work. This is especially important for Internet of Things connected devices, which generate massive amounts of data.   Fog computi...
